I need a joystick for my ipad and this seems like such a great idea so i ordered two flying rc heli simulator on the ipadthe idea is that it is like a brush of touch hairs on a dome shaped bottom when you tilt the stick the concentration of hairs moves the effect should be the same as if you slightly rolled the point of your finger

It actually do work some of the time but then suddenly it will loose connection and center the stick while my stick is full tilt
